Daubeny's Teaching Display Board of Atomic Weights
The Museum of the History of Science, Oxford, has a display of Charles Daubeny's teaching materials from 1831, including a black painted wooden board with "SYMBOLS OF SIMPLE BODIES": symbols, atomic weights and names of elements in two columns, and a small pile of cubes with element symbol.
Note that some of the numbers seem very strange to our eyes: carbon is given as 6 (rather than 12) and oxygen 8 (not 16), while others correspond with modern values remarkably well, chlorine is given as 36 rather than 35.5.
Daubeny's weights (along with the modern mass) are given:
